BRASS-PLATED STEEL WIRE FOR REINFORCING RUBBER ARTICLES AND METHOD FOR MANUFACTURING THE SAME

摘要

Problems to be solved by the invention: It is an object of the present invention to provide a brass-plated steel wire for reinforcing rubber articles capable of surely improving adhesiveness between brass-plated steel wire and rubber and a method for manufacturing the same. Means for solving the problem: A brass-plated steel wire 10 for reinforcing rubber articles according to the invention comprises a steel wire having a brass-plating layer 11 thereon, wherein the brass-plating layer 11 has an amorphous portion 11a formed of crystal grains having a grain size of 20 nm or less. It may also be such that the brass-plating layer 11 is of a laminated structure 13 of an amorphous portion 11a on the surface side and a crystalline portion 11b on the inner side, wherein the amorphous portion 11a is formed of crystal grains having a grain size of 20 nm or less and the crystalline portion 11b is formed of crystal grains having a grain size of more than 20 nm.
